SPECT technique might measure absorbed tissue dose from radiation therapy

Example of a new CZT digital detector technology SPECT system, the GE Starguide SPECT-CT system on display at RSNA 2022. The system uses arms that extend to the patient so the detectors are closer to the photon emission source inside the patient to improve image quality.

Washington University is using a novel low-count quantitative SPECT technique to measure the concentration of alpha particle radiopharmaceutical therapy activity in the tumor and in radio-sensitive organs.
